This invention relates to a ditcher back-v and thence to a;drum'30, towhichthefrefiller, having a hoe for scraping back into maining end ofthe vcable is secured. a ditch the earth previously removed there- The outer end of the long arm 17 of the from, by the machine arranged as a ditcher. le ver 15 presents ears 31, on which may be 5 The invention will be best understood by hung either a.l scoop for digging a ditch, or reference to the following description, when a hoe 32, now to be described, for scraping taken in connection with the accompanying the earth back into the ditch. Referring drawings of one specific embodiment thereto Fig. 5, the hoe in the present example of, while its scope will be ,more particularly comprises generally a scraper 33 and an arm pointed out in the appended claims. or handle 34.

The holes to and part-way around a sheave 28 carried 42 in the ears 41 receive a pin 48 for a block by the block 23, thence in the first direc- 49 interposed between said ears. A hauling 5'0 tion to land part-way around a sheave 29, cable 50 (see Fig. 1) is anchored as at 51 m" on the block, and extends thence in the directions of the arrows thereon to and part-way around a sheave 52 (see F 3) carried by the boom, thence in the opposite direction to and part-way about a sheave 53 in the block 49, thence in the first direction over a sheave 54 (see Fig. 3), and finally to and about a drum 55, to which the remaining end of the cable is secured.

The operation will now be described, reference being had to Fig. 1. Starting with the parts in the position shown in Fig. 1, the hauling cable 50 is wound in onto the drum 55, and the hoisting cable 21 is correspondingly paid out, as a resultof which,

the hoe is. pulled horizontally toward the and downwardly about the pivot 16, and that. the upper end of the boom swings inwardly machine with as much as is desired of the weight of the lever'15 and the boom 10 upon the hoe, it being understood, of course, that the outer end of the lever swings inwardly and upwardly about the pivot 1l. By proper manipulation of the two cables, the'hoe can be caused to travel in any desired path across the pile of earth, and to scrape it 'into the trench or ditch'. Reverse travel of Y the hoe is caused by winding in on the hoistthereto, what I claim and desire by Letters f Patent to secure is:

1. In a ditcher back-filler, the combination of a hoe having a generally upright scraper Y and a generally horizontal arm, the latter comprising two spaced members, a block interposed between said members and having` pivotcd to turn about a horizontal axis, a boom on which said supporting arm is pivoted to swing about a horizontal axis, means l a sheave, a supporting arm 4onwhich said v -zontal axis, a boom on which said support- 45 members are pivotcd to turn about a horiing arm is pivotcd to swing about a horizontal axis, a support on which said boom is pivotcd to swing about a horizontal axis,
